Slider

I fell in love with the Aldehyde theme !!! It is gorgeous. But, and this is a big but, I can’t get it to look like the demo. When I try to load a header it comes back with an error when I try to crop so my header image is way to large. I also can’t find where to put text for my header images and how to make them parallax text. I so hope someone can help me as I really want to use this theme.
